I just recently purchased a VXR (2006) and I've noticed the fuel gauge is stuck on quarter, the rev counter is 1000rpm ahead and the speed is also 10mph ahead.

Sent it to an auto electrician and he didn't pick up any faults!! When you start the car the needles do the usual backwards and forward thingy.

I don't really want to sent it to vauxhall! Any ideas or tips what I can do please????
